What we work on
- 01
Diagnostics
A check-engine light or a strange noise gets traced to its actual source before any part gets ordered or replaced.
- 02
Brakes
Pads, rotors and calipers inspected and replaced, with the worn parts set aside so you can see the wear yourself.
- 03
Engine repair
From a rough idle to a full rebuild, engine work is diagnosed first so you're not paying to guess.
- 04
AC service
AC blowing warm or weak gets checked for leaks and pressure issues before refrigerant goes anywhere near it.
- 05
Smog & inspection
Smog checks and pre-purchase inspections done on the lift, so a problem gets caught before it becomes yours.
- 06
Batteries & electrical
Slow cranks, dead batteries and wiring gremlins traced with a meter, not swapped parts and hope.

Diagnosis before repair
Nothing gets replaced until the actual cause is found and shown to you.
Straight explanation, no guessing
You hear what's wrong and why before you're asked to approve any work.
Fit for the vehicle
Repairs are matched to how the vehicle is actually driven, not upsold beyond that.
A working garage that shows you the part
Wholesale Performance Muffler runs out of a plain industrial shop in Escondido — painted concrete floor, steel lift columns, corrugated metal walls, tools where you'd expect tools. Jake and Tony work on everything from older trucks to daily drivers and diesels, and the shop's reputation runs on the same thing customers keep repeating: they'll tell you what's wrong before they touch anything, and they'll show you the part that failed. If it can wait, they'll say so. If it can't, you'll see why.
“The owner, Jake, is the absolute best and only person I trust to work on my diesel trucks and gas vehicles. He’s honest, extremely fair and meticulous about his work.”

“Bought a new Ram Promaster 3500. Tail pipe was clamped on and came off on the 15 coming home. Jake had a lift that could lift my adventure van and did a great job welding a new one on.”

“The only place I fully trust to work on my vehicles especially after having dealt with three other dishonest shops in the past two years.”

Questions
Will you tell me if something can wait?
Yes. Part of the diagnostic process is separating what needs attention now from what can be watched and handled later, so you're never paying to fix something that isn't urgent.
Do you work on diesels and older vehicles, or just newer cars?
Both. The shop handles gas and diesel trucks, older vehicles, and newer daily drivers, and diagnoses each the same way — a hands-on check before any repair is recommended.
How do you decide what a repair actually costs?
The cost follows the diagnosis. Once we've found the actual issue and shown it to you, we go over what the repair involves before any work starts, so there's no surprise once the vehicle's back down off the lift.
